[2:06:20][Q&A][:speech]
[2:06:45][@thestalkingwolf][Q: Will you do all the platform layers or leave that to the community support?][:"platform layer"]
[2:07:11][@0lpbm][Q: Will you add some randomness to the sizes (and maybe shape - skewing, height / width) of the trees?]
[2:08:06][@ormone88][Q: What do you think about using the mouse wheel in order to drag values in the editor? In this way it wouldn't be limited by the screen space. Also, you could use something like Alt + mouse wheel for doubling the increase / decrease rate][:"input handling" :ui]
[2:08:35][@x13pixels][Q: Are you doing more Meow Hash later tonight?]
[2:09:35][@thestalkingwolf][Q: Having just dealt with weighted distributions and cumulative sum draw, will you add weighted selection to the tree selection, i.e. some trees may show up more or less common?][:"asset system" :statistics]
[2:12:14][@wolverinegator][Q: Left-click normal speed, right-click double speed dragging? Or some modifier key that the pen also has][:"input handling"]
[2:12:43][@ormone88][Depression-oriented programming is the future][:health :language]
[2:13:35][@0lpbm][Q: I have watched an older episode where you were coding player :movement related to a moving translation point. Will there be any in-game elements using this mechanic?]
[2:13:57][@Brian][Q: Is the idea that the monsters from Anna Draws It going to be in [~hero Handmade Hero]? Or at least potentially?][:art]
[2:14:06][@0lpbm][Will there be any in-game elements using this mechanic?]
[2:14:47][@0lpbm][Q: Moving translation points (the points where the body moves to)][:movement]
[2:15:39][@theflame937][Q: What is your go-to method to hide a string in a project?]
